Dandong Bettersize Laser Particle Size Analyzer Bettersize2600e
Bettersize2600E is a simplified version of the Bettersize2600 laser particle size analyzer. By appropriately reducing the cost of the high - cost combined forward and inverse Fourier optical system, this new particle size testing technology with high precision and wide measurement range is applied to the economic dry - wet laser particle size testing field, achieving an "economical" price but "uneconomical" performance.
The combined forward and inverse Fourier optical path system adopted by Bettersize2600E is characterized by using a single laser beam to receive the scattered light signals at large forward and side angles, thus enabling accurate particle size testing of sub - micron, micron, and sub - millimeter samples. At the same time, the instrument also adopts technologies such as automatic centering, anti - dry - burning ultrasonic dispersion, SOP, and polarized light, achieving a "high - end" configuration for a low - end instrument.
The Bettersize2600E laser particle size analyzer has both dry and wet testing functions. For conventional samples, it is equipped with a water circulation dispersion system, making it a wet laser particle size analyzer; for samples such as easily soluble (e.g., pharmaceuticals), magnetic materials, and cement, it is equipped with a dry dispersion system, making it a dry laser particle size analyzer. For users with both types of samples, the conversion between dry and wet methods is extremely convenient and fast. This instrument is mainly suitable for particle size distribution testing of micron - sized powder materials. In addition, the wet system has special functions such as automatic testing, automatic water intake, automatic water drainage, automatic bubble elimination, and automatic cleaning; the dry system has functions such as automatic pressure adjustment, automatic sample injection, automatic dispersion, automatic testing, and negative pressure monitoring. The intelligent design not only simplifies the operation and improves efficiency but also ensures the repeatability and accuracy of the test data. This instrument is particularly suitable for enterprises engaged in the production and application of conventional powder materials, as well as laboratories in universities and research institutes.

Outstanding features
● Dual wet and dry method technology: The uniquely designed test chamber compatible with wet and dry methods allows for convenient and fast conversion between wet and dry methods. The air inlet and outlet channels designed according to the aerodynamic principle prevent the lens from being contaminated. Suitable for all samples.
● Lens: A large-aperture cemented achromatic lens is used, which increases the angle of receiving scattered light and has good resolution for scattered light generated by both large and small particles.
● Technology to ensure repeatability: The random function recognition technology and high-speed pre-amplification technology are adopted to keep the signal stable, thus ensuring the repeatability and accuracy of the system.
